I've done 100+ with mine and had no problem with the filters flying off. They're on there real tight.moto said:don't cha think they'll blow off around a 100 or a 110 mph? or they may not make it that fast. shouldn't you put a nipple inside the abs fitting? auto zone sells one that will fit in there it shaped just like your abs fitting and its made out of aluminum. don't get me wrong i love the idea and plan on doing it my self, just don't know how the boots made out of rubber are gonna hang around at 100 mph.
